Cheryl might be unlucky-in-love but after a string of failed relationships she's noticed a pattern.

The 35-year-old mum-of-one admits the real reason she's single is because she "tolerates too much".

"I think I love too easily," she admitted.

"I think I tolerate too much. I don't set clear enough boundaries in the beginning."

Giving an interview to promote her first single in four years, Love Made Me Do It, Cheryl also hinted that Liam Payne broke up with her rather than the other way around.

She said: "You can’t rely on someone to make you happy.

"I might want somebody else to be in my life but if they don’t want to be in your life, what are you supposed to do?"

She also insisted there is only man she needs in her life right now – her son Bear.

The singer, 35, said she has “zero” desire to start a new relationship following her split from the 19-month-old’s dad, Liam Payne.

And she said Bear makes her feel truly happy for the first time in her life.

Cheryl said: “My heart’s full, I’m fulfilled.

“I’m not looking for anything any more. I’m whole. I’ve got the man of my dreams.”

She also admitted her obsessive relationship with Bear could “maybe” have been a reason for the breakdown in her relationship with Liam – who she credits as the only man to have been faithful to her.

Asked if the 25-year-old One Direction star felt left out, she said it was possible, adding: “When I think back to new motherhood, I was in such a bubble of love, I don’t think I saw anyone else.”

And the former Girls Aloud star stressed romance was not a priority after her split with Liam and failed marriages to footballer Ashley Cole, 37, and restaurateur Jean-Bernard Fernandez-Versini, also 37.

Cheryl said: “I would never say never. But I have zero desire to start up a new relationship.”

Bear now sleeps in her bed every night, which she calls “the best thing in the world”, as she doesn’t want to leave him to sleep on his own.

She told the Sunday Times: “I would spend every breathing moment with him and not do anything else. But I know that’s unhealthy.”

The video to her single sparked rumours that she is using facial fillers and Botox, and she stunned fans with the new look – inc­­luding a bob hair style – in London on Friday.

But she said: “My whole body, even my face, everything’s changed since Bear was born.”
